Necromancy. Stuff flying and lasers. Stuff helping people. I'd rather take over the world NOT single-handedly. Maybe, two billion-handedly? And, come on. What could be better than controlling shadows and the dead?
I find that powerlisting.wikia.com is a big help. Based on this, Mysticism is the best non-omnipotent superpower. It breaks down to nearly every power, including psychokinesis, soul absorption, creation, elemental manipulation, life-force manipulation, and many, many others. Look for yourself. It's awesome.
teleportation, telekinesis, or telpathy. all Ts!!!!
Ooh, this just gave me a though. Could an advanced telekinetic hypothetically open up a rift in the space-time continuum, thus creating a portal for teleportation?
